What I'm looking for

I’m looking for a team where I can own backend services end to end—making architecture trade-offs, delivering high-load low-latency systems, and building production observability and secure deployments (mTLS, CI/CD). I thrive with distributed systems and infrastructure rigor.

I’m a backend engineer focused on distributed systems, production infrastructure, and high-load, low-latency services. Across 5 years of commercial experience, I’ve shipped backend solutions for electric-vehicle telemetry, service mesh platform infrastructure, retail pricing control, crypto payments, utility billing, and public digital services.

In my current role, I build production backend services that keep vehicles securely connected to the cloud and integrate external clients across low-latency MQTT, gRPC, and API flows. I independently drive requirements discovery, choose architecture through trade-offs, implement core services with tests, and deliver CI/CD-ready releases—while building observability and strengthening security with mTLS and certificate-based authentication.

Previously, I worked on a heavily customized Istio fork and adjacent Kubernetes components, restoring automated testing and raising unit-test coverage to 80% while expanding integration tests to ~95% of critical functionality. I also design and build test infrastructure (parallelized Kubernetes environments and CI reporting), repair CI/CD pipelines, and mentor interns—so quality and reliability become repeatable, not manual.
